What can I find here?



What the heck is an N7RK?

I am an amateur radio operator. My call letters are N7RK. Amateur radio operators are also known as "hams". Hams talk to each other via radio using Morse code, voice, teletype, and other digital modes. Some hams also contact and see each other with amateur TV. Hams also have their own satellites and communicate using the satellite as a form of repeater. I prefer to work Morse code which is known as CW although you will find me on phone occasionally. I do enjoy working DX on 75 meter phone.

I have been a ham since 1963. My first call was WN6IWX followed by WB6NRK. I liked the "NRK" enough that I changed my call to N7RK in 1977 in the first vanity call sign program. Here are some pictures of my stations over the years including my first station.

W6BAM, Shelley Trotter who is now a silent key got me started in Ham Radio in 1963. He was licensed in 1926. Here are some photos of his 1920's ham station along with a few other early photos

I also enjoy collecting and restoring antique ham radio equipment which include communications receivers and transmitters. In old radio circles, these radios are known affectionately as "Boatanchors", as most of them are heavy enough to anchor small boats. Back in the 1970 and 1980s when all of the solid state Japanese radios came into vogue no one wanted the older gear and due to their weight, other hams would say "use it for a boatanchor." I especially enjoy the pre-war and early post-war receivers by Hallicrafters and National such as the classic National HRO-5 shown on the right. Here are pictures of some of my boatanchors and broadcast radios

More Radios and Boatanchors

Breting Radio Company

I recently finished reworking a Breting 12 receiver from 1935. As a result of this, I have put together a page on the Breting Radio Company showing their line of receivers and a page showing my Breting 12. Follow this link for the Breting Radio Company web page.

Howard Radio Company

I presently have four Howard receivers and was unable to find much about this company. I put together what information I do have and it is presented here in hopes that some other collectors will find it useful. Follow this link for the Howard Radio Company web page.

Patterson Radio Company

I also have three Patterson receivers and have very little about this Los Angeles company. I have put together what information I do have and it is presented here in hopes that some other collectors will find it useful. This is under construction and new photos and schematics will be added.

Follow this link for the Patterson Radio Company web page.

My main interest in ham radio is DXing. DX stands for distance and DXers are hams who enjoy talking to other hams all over the globe. I am on the "Mixed" DXCC Honor Roll with 356 countries worked and 352 confirmed. Mixed means I have worked the countries on both phone and CW. My other significant achievement is WAZ # 22 on 75 meter phone. This is very difficult on that band. I received that award in 1982 and at the time it was only the 5th one that had been issued in the USA and the first one outside of California. As of 1999, they have only issued about 70 of this award. My favorite band is 80/75 meters where I have worked 269 countries with 265 confirmed. I also enjoy DXing on 160, 40, 30, and 12 meters also.



I was the DX when I visited "The Rock" of Gibraltar in 1994 and operated ham radio as N7RK/ZB2. Here is my QSL Card with a view of the rock from Spain.

Want to know more about Amateur Radio?

Being a DXer, I like to frequent DX related sites to find out what bands are open and who is on. I am a member of the Central Arizona DX Association - CADXA.

Be sure and visit the CADXA Home Page.

Growing up, I loved watching Laurel and Hardy on Saturday mornings. Thanks to DVD's and video cassettes, I can still watch Stan and Ollie.


Here are some good Laurel and Hardy websites.
